I did this and this made Typo not work at all. So much that I had to delete the entire directory and re-upload Typo for it to work again. I even tried using killall -USR1 dispatch.fcgi and killall -9 dispatch.fcgi and that didn’t fix it; when I added the above code my site stopped responding and eventually gave 500 errors.

So I don’t know what else to do. I have seen people say they no longer get 500s, but I certainly do, and I’ve followed everything they’ve said.
